Description of the new type: [Technical field to which the new type belongs] This creation is about a retractable wheelchair securing structure, especially a retractable wheelchair that can be secured through the securing structure after the wheelchair is stretched. The designer who fixes the card and can fold it quickly and easily during folding. [Prior art] Among the wheelchairs of the present order folding type, there is a kind of case as shown in Announcement No. 5470702, which is arranged in the hinged seat between the exhibition hall and the collapsed hall. The connecting tube is equipped with a control pin-controlled pin cup, and the pivot seat is provided with a fixed block with a positioning hole, which is used to support the grains on the base of the pin. The hole in the end came. Underneath the seat cushion, the dreadlocks are intricately concealed and only hidden. [New content] When it is more convenient, the traditional folding wheelchair can be simplified, and the installation is not easy. Action to make folding up faster. Its structure on M275834 = including clips and interlocking cables, and it is set on the frame of folding wheelchairs: folding wheelchairs are added to form, points, and the card is consolidated. The tonnage contacts of the card 18 are those of the middle buckle, the positioning recess D, and the frame buckle of the folding wheelchair. The other purpose of this creation is to provide a design that can be used to retract or retract the wheelchair through a vertical control link to facilitate the design of the foldable or stretchable wheelchair. ^ It is a two-tight or _ control11, which can be controlled by a control system installed elsewhere. Suo Zhila, release the action. The purpose of the original creation is to provide a retractable position ^ The skeleton field of the retractable wheelchair is set corresponding to the ^ notch of the card and [actually: the positioning notch of the type Γ clip is fastened. —As shown in the figure, the creative system includes clips (1) and linkage cables (2), and is set on the frame (3) of the folding wheelchair, where the β frame ⑶ includes the backrest rod (31 ), Chair Lin (32), rear wheel lever ⑽, front wheel lever (34), connecting rod (35) (35,) and lift lever (36), the front lever (31) is connected to the front wheel lever ⑻ =, and The backrest rod (3) extends—connecting the lift rods (36) on the two sides, and pivotally located at the lower end of the moon cup (31) —the pivot piece (311), which is connected to the rear wheel rod ⑽, and = The rear wheel lever (33) is provided with a suitable positioning section (331) [in this embodiment, the positioning & (331) wire is separately provided as an example. 'In actual implementation, it can also be framed by bone M275834 ( 3) The upper two sides are directly connected by the rear wheel lever (33)]; and the seat wheel post (32) and the front wheel lever (34), and the front wheel lever (34) and the rear wheel lever ⑽ There is a connecting rod (35) (35 '); the clamping piece ⑴ is pivoted on the shooting rod of the skeleton ⑶ 31) forming a pivot joint οι), and a positioning notch ⑴ is provided on the fixing piece ⑴, and the positioning notch (12) is opposite to the skeleton (3) and the positioning provided on the wheel lever (33) The segment (331) snaps into place. Linking cable (2)-the end is connected with the clip ⑴, the other end is set on the lifting rod (36) of the skeleton • ⑶, and-the controller (21) set on the upper end of the backrest rod (31) ) Is connected, and is controlled by the grip and release of the controller (21), and the interlocking cable (1) is rotated around the contact point (11). By this, in the normal positioning and positioning, the card m piece 枢 pivoted on the seat back lever ⑻ and the rear wheel lever (33), with its positioning recess σ〇2) is directly stuck to the convex extension The positioning segment ⑽) of the rear wheel lever ⑽), so that the shooting lever ⑻ and the rear wheel lever ⑽ can be supported by the fixing piece ⑴, so that they can be stretched and positioned with each other; The notch of position 〇2) is directly and firmly embedded in the positioning section (331). The positioning of each other is quite accurate, and there is no danger of accidental disengagement leading to collapse. For example, when folded, as shown in Figures 4 and 5, the controller (21) can be directly held against the controller (21) to rotate the linking cable ⑵ to rotate the locking plate ⑴, so that the locking plate ⑴ will be inserted with it. Point (11) is rotated for the center of rotation, causing the positioning notch ⑽ on the retaining piece ⑴ = the positioning section 退 on the rear wheel lever 退) to be dismantled, and then the moon lever (31) is opposite The rear wheel lever (33) and the front wheel lever (34) are folded and abutted, and the reduced volume is reduced. M275834 And the lifting rod (36) extended at the rear end of the backrest rod (31) of the skeleton (3) can be used by the user to directly extract the entire skeleton (3), so as to facilitate the transport of the carrier. However, the above are only the preferred embodiments of this creation. When this ca n’t be limited, the scope of this creation is only applicable, that is, the simple things such as the scope of the patent application for this creation and the new month. Effective changes and revisions should still fall within the scope of this creative patent. [Schematic description] The first picture is a schematic diagram of the structure of this creation.
